Hysterical aphonias refers to a condition where a person suddenly loses their speaking ability without any apparent physical cause. This condition is also known as psychogenic aphonia. It is common in people who have experienced severe emotional or psychological trauma. Some synonyms for hysterical aphonias include functional aphonia, conversion aphonia, and pseudohypertrophic laryngitis. These terms describe the same condition whereby the loss of voice is not due to any organic or physical reason. Treatment for this condition involves addressing the underlying psychological or emotional cause of the symptom, such as through counseling or therapy.
